OSCam: Cheapest smart card reader

With a price under $3 it is able to read/write SIM cards so I bought one to test if I can use it also for standard decrypt cards reading.

When it came, I disassembled it and checked what’s inside. It contains one unidentified chip with 12Mhz crystal (USB to serial converter) and 74HC04 with 3,579Mhz crystal (oscillator used as card clock)

3,579Mhz oscillator fits my decrypt card so I soldered smart card socket (bought from ebay) and put my card in. If your card requires other frequency, you should be able to change it just by soldering correct crystal.

This design reminded me smartmouse/phoenix design so I gave it a try and after some fiddling, I found out correct oscam settings:
